Detailed Description

The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, and the illustrated embodiments are only for explaining the present invention, and do not limit the scope of the present invention.

The utility model discloses a tongs is connected with the robot, and it is fixed that the robot passes through pedestal mounting, and the robot includes a plurality of arms, corresponds arm position installation and drives arm pivoted motor, and each motor cooperation electric robot drives the tongs and moves at multi-angle range. The tongs include the pneumatic clamping jaw of single-handed tongs, two fingers centre gripping, adopt a robot tongs to press from both sides the cross promptly, every robot tongs corresponds the start-up clamping jaw that adopts two fingers, carries out material loading and unloading to the cross through cylinder, robot cooperation. The clamping or loosening action of the clamping jaws places or removes the cross shaft into or from the jig.

The tongs include carousel, cylinder and clamping jaw fixed block and clamping jaw, and the carousel is connected with the robot, and the one end and the carousel of cylinder are connected, and the carousel is connected with the arm end of robot, and the robot can drive the carousel and rotate the action, the position precision of adjustment clamping jaw. The other end and the clamping jaw fixed block of cylinder are connected, install two pneumatic clamping jaws on the clamping jaw fixed block, relatively speaking, two clamping jaws can realize getting the clamp of cross axle, reduce the quantity of clamping jaw as far as, when guaranteeing the installation accuracy, also consider size structure, the narrow space restriction in scene, the not allowed takes place to interfere with equipment, because of the restriction of work piece clamping position, only design two clamping jaws can.
